There we were minding our own business and suddenly folks were hearing voices inside their heads. Why did god bother us? According to the stories you had blokes building bloody big boats and others threatening to murder their own kids, all in the name of some so-called divine source. Human beings had journeyed for billions of years from single cell entities to multicellular, then, to mammals to primates, but of course were not equipped to remember such deep time events. So we made up stories to populate our own shallow-time historical concerns with important people and a god to top it all off with.
